- I Patented Sept. 3, 1907. i

Original application filed June 16,1904, Serial No. 212,819. Divided andthis application filed September 23,1905.' Serial Ro. 279.887.

To atl :whom 'it 'may concern:

Be it known that I, HERMANN Gnoasn PAPE, a citizen'of the United States,residing at New York, in the county of NeW York and State of New York,have invented a new and useful Automatic Circuit-Closer, 'of which thefollowing is a specification.

This invention relates to a novel telephone receiver constructed withspecial reference to its use as the earpiece-of an audiphone set, whichlatter is used as an aidv to defective-hearing, and comprises anearpiece electrically connected to a sound receiver corresponding infunction with the transmitter of a telephone ap-l paratus". The presentapplicationA is a division of one filed by me on .lune 16, 1904, SerialNo. 212,819, which has now eventuated in a patent granted on October 3,

1905, and numbered 800,675.

The primary object of the present invention is to provide in connectionwith a receiver and head band therefor, an automatic circuit closercoperating with i i the head band to close the circuit through theinstru-` Ament when the band is placed upon the head to posi- 'tion thereceiver at the ear.

Several embodiments oi the invention are disclosed` partially in sectionof another embodiment of the inv vention, and Fig. 7 is a View inelevation of still another form.

Similar reference numerals are employed to designate corresponding partsin allthe figures of the drawings. A i

In the embodiment illustrated in the first four figures, a receiver isshown generally at 8 and comprises a casing within which are located theusual diaphragm,

9 and 'magnet 10. This receiver is mounted upon one end oi a supportingdevice inthe form of a head band 11 comprising pivotally connected bowedsprings, said band at one end having an extension plate 12 pivotallyvconneted to the springs and terminating at its free end in a hook3. Theplate 12 extends across the rear side of the receiv'er, and the hook 13has a detachable and pivotal engagement in a keeper 14 carried by .therear wall of the receiver casing.

-Located within the casing is a circuit closer having the usualconnections with the magnet and leads, said circuit closer in thepresent embodiment consisting of a pair o yielding .Contact springs 15,each of said springs being secured to the 'rear casing wall, as shown at16, and having their free ends disposed in overlapping relation. Anactuating device consists of a plunhowever, the apparatus is-applied tothe head of an operator or wearer, the bowed head band is sprung apart,and when the receiver is placed against the ear, the tension of saidhead band is sufficient to overcome .the tension of the spring 15 thatbears againstthe stem,

so that said stem is forced inwardly and the Asprings are brought` intocontact with each other thereby closing the circuit. It `will thus beseen that an Iexceedingly simple structure is provided, whereby, uponthe application of the apparatus to the head of a wearer, the contactwill be automatically made.

A slightly different form of structure is illustrated in Fig. 5, whereinthe receiver is shown at 20`and the head band at 21, said head bandhaving the usual extension 22 pivotally connected, as shown at 23, tothe receiver. Mounted on the rear outer side of the receiver casing is aspring contact 24 having a head 25 borne against by the extension 22. Acontact, shown diagrammatically at 26, is disposed in-the path of ymovement of the spring 24. The operation of this device will be obvious,and it will be apparent that the wherein the receiveris shown ata-27.The head band is designated 28 and has an extension 29 which in thisinstance is of a yielding nature and is rigidly fastened, as shown at30, to the rear casing wall, the fastener also constituting a bindingpost. The resiliency of the extension 29 permits the relative movementof the receiver and band, and said extension is provided with a contact31 that is moved into and out of engagement with another contact 32secured to the rear wall of the receivercasing, as shown, and having itsouter end disposed in the path of movement of the contact 31.

Still another modification that involves4 the same basic feature isshown in Fig. 7, wherein a head band 33 is illustrated, having at oneend a receiver 34 and provided at its other end with a contact spring35. This spring lis secured to the adjacent end of the head band by asuitable clamping bolt 36 passing through I the two and through suitableinsulation 37 that separates the spring 35 and the head band. Thebolt 36is insulated from theA head band, but isinelectrical engagement with thespring 35, and connectedf) said bolt is a lead 38, the other lead beingconnected dircctly to the head band, The head band 33 is of greaterresiliency than thespring 35 and consequently it will be apparent thatwhen the structure is applied, the said headband will be moved towardthe free end of the spring 35. Said free end is therefore provided witha contact piece 39, and a corresponding contact 40, carried by theadjacent portion of the head band, is consequently movable into. and outof engagement with the vcontact 39. v

From the foregoing it is thought that the construction, operation, andmany advantages of the herein described invention will be apparent tothose skilled in the art, Without further description,'and it will beunderstood that various changes inthe size, shape, proportion, and minordetails of construction may be resorted to without departing fromA thespirit or sacrificing any of the advantages of the invention. In thisconnection it may be stated that whilethe invention is particularlyuseful in connection with audiphone sets, as above described, it willstill be apparentthat its application is not limited in this respect, assaid invention may be employed for a variety of purposes.

Having thus described my invention, what l claim and desire to secure byLetters Patent iszi. The combination with a receiver, of a circuitcloser, und a head band for the ,receiverconstituting operating meansfor moving. the switch to closed position upon the positioning of thehead band and receiver upon an opera tor.l

2. The combination with a receiver', of :i circuit closer, and u curvedspring head bad for the receiver' constituting a support for the same.said band also constituting operating means for moving the switch toclosed position upon the positioning of the head band :ind receiver.

3. The combination with a receiver', of a head-engaging support for thereceiver movabiy connectedat one end to the same, und a circuit closerhaving a portion interposed between the receiver and support undoperated upon their relative movement.

seines@ 4. 'lhe combination with avreceiver, of a head-engagingsupportfor the receiver movabiy connected with the same, and aci-rcuit closerincluding an element carried by the receiver, and an element actuated bythe headengaging support upon the relative movement of the receiver andsaid support. The combination with a receiver, of a bead-engagin supportfor the receiver movably.associated with the same, and a circuit closeractuated upon therelative movement -ofthe receiver and said support.

G. The combination with a head engaging device, of a i'eceiver movablymounted thereon und a circuit closer mounted within the receiver, saidcloser comprising a pair of yielding contacts, and an actuating stemprojecting from the receiver and operated by the head engaging device.

7. The combination with a spring bead band, of a receiver movablymounted upon one end of the same, a circuit closer located within thereceiver, and an actuating stem for the closer slida-bly mounted in thecasing and having a head borne against b v the head band.

S. 'lhe combination with a receiver including a casing, of a head band.a circuit closer operated by the head band, and a detachable pivotalconnection between the head band and'casing. A

`9; 'lhe combination witira receiver including u vcasing having akeeper, of a head band provided with a terminal hook engaging the keeperto ettect a hinge connection between the receiver' and band, anducircuit closer including.

an element interposed between the receiver and band and operated on therelative swinging movements thereof.

10. 'ihe combination with :1n-instrument of the class described. of acircuit closer arranged within.the circuit thereof, and a bend-engagingsupport, said head-engaging support constituting a part of the circuitcloser.

ln testimony. that l claim the foregoing as my own, I have heretoniiixed my signature in the presence of two witnesses.
